there is a theory that Chara was menatlly depressedbc of murder, and wanted to kill herself or something, so when she heard the rumor of mt ebbot, she jumped down,never changed oersinalities

Well she's nice not evil because I think asriel says I should d have laughed it off like you.everyone in the game because they've had a miserable life,not because they're evil.they're life changed when asgore was poisoned by the buttercup flowers,they,Chara died because aerial made a deal to bring them through the barrier.Asriel dremmur thought that he could free all the monsters in the underground by doing this.

The humans thought Prince Asriel killed Chara when Chara only wanted Asriel to bring them back to the flowers.Asriel absorbed chara's soul btw.The humans showed no mercy toward Asriel.Prince Asriel came back with blood and scars and such and such.Asriel put Chara down on the flowers in the thrown room,Asriel died next to chara.Queen Toriel and king Asgore found them dead.Queen Toriel buried Chara where they fell.
When Chara was buried there the flowers bloomed.Then frisk came..
